I looked into getting that last year after purchasing my jeep but ended up picking up some Meguirs Natural Shine Protectant instead. Does the same thing from what I can tell and won't dry out the plastic like Armor all will.
I only use Lexol to clean and condition my leather seats. Its a pricey product but I've been using it for years in my vehicles and have been very happy. They make a cleaner (orange bottle) and a conditioner (brown bottle).
